Introduction
The Nitropolis slot series continues with its post-nuclear storyline and unique gameplay. There is a reason why ELK continue with this series, and that becomes evident as you start spinning the apocalyptic yet light-hearted reels.
Sounds like a contradicting description, right? Well, that’s all part of the Nitropolis appeal. Animal gangs, nitro reels, multiple bonus symbols, free spins, super free spins, and much more can be expected, not least the potential top win worth 50,000x your stake.
Theme, Graphics & Soundtrack
If you have played the Nitropolis games before, you will know what to expect in terms of visuals, the gangs of animals, and the general dystopian world that ELK has created. Again, it may sound a bit dreary in words, but the resulting gameplay is a lot more enjoyable in this futuristic slot theme.
The random beach location may confuse a few players, but the general design generates an experience that connects to the theme. However, the upbeat soundtrack would not feel out of place at a beach party, so perhaps there is some link to be found there, albeit quite tenuous!
Nitropolis 3 RTP & Volatility
Nitropolis 3 has an RTP of 95% and provides high volatility gameplay.
Nitropolis 3 Gameplay
How to Play
A quick overview of the controls in ELK’s Nitropolis slot:
- Big spin button that starts the game
- Use the coin logo to finetune your bet total
- The rules, paytable, and bonus features are all located within the main menu
How to Win
The Nitropolis 3 game grid starts with six reels and four rows. The avalanche/cascading mechanics mean the number of rows increases with every avalanche win up to eight rows. The avalanche feature purely means that all winning symbols disappear for new symbols to fall into place. But as we alluded to earlier, this game also adds another row with every win, meaning you could play on a 6x8 slot grid.
The slot grid in Nitropolis 3 is filled with a big collection of symbols, ranging from low to mid and high-paying icons. Not only that, but you also get multiple wilds, scatters, and bonus symbols too
Nitropolis 3 Nitro Reels
The nitro-filled bonus reels are recognized by their luminous green border and essentially come with reel modifying abilities. The “small nitro” reels cover a total of two symbol positions and include anywhere from 4-12 instances of the same 1x1 symbol.
The more rewarding “big nitro” reels cover six symbol positions and include 2-6 instances of the same 2x2 symbol.
Free Spins
The free spins bonus game starts off quite standard, but that super bonus game is only one symbol away, so let’s explain how it works. Landing three airship scatters or more will trigger 8-20 free spins. The super bonus game is activated if one of the airship scatters is a super airship scatter.
A couple of extra features are thrown into the bonus game to keep the action levels high. All Nitro Reels are sticky for all free spins, and all new ones simply stack on top of each other.
The safety level (the “do not cross” bar) rises by one row with every winning spin and sticks for all remaining free spins. In other words, you get more winning chances when the bigger grid is active.
